IMPROVEMENT IN REFRIGERATORS.

Specificationforming part of Letters Patent No. 1 12,] 91, dated August26, 1873; application filed.

August 7, 1873.

To all whom it may concern:

Be it known that I, ALFRED BARDELL, of the city, county, and State ofNew York, have invented a new and useful Improvement in Refrigerators;and I do hereby declare the following to be a full, clear, and exactdescription thereof, which will enable those skilled in the art to makeand use thesame, reference being had to the accompanying drawing formingpart of this specification, in which draw- 1ng-- Figure l is a centralvertical section of myimproved refrigerator. Fig. 2 is a top view takenwhen the cover has been removed. Fig. 3 shows part of the index on theice-reservoir.

' Similar letters indicate corresponding parts.

This invention consists of a refrigerator whose ice reservoir isarranged to revolve within the wall of the refrigerator, supported uponthe top of said wall by means of antifriction rollers, which allow theice-reservoir to be turned around forward or backward. From the bottomof the reservoir descends a tube, which enters a central opening madethrough the bottom of the refrigerator. This tube serves to dischargethe water that comes from the melting ice, and to center the revolvingice-reservoir within the refrigerator, and also to support the shelvesof the apparatus. The ice-reservoir has double walls at its upper part,and the space inclosed between such double walls forms an air space,whichis put in communication with the interior of the ice-reservoir byholes through the inner wall to admit the cold air, which is conductedfrom the said air-space down into the chamber or interior of therefrigerator by means of perforated air-tubes, which extend downwardinto the refrigerator and serve to support the outer edges of theshelves.

The refrigerator is in this example made circular, and has a door in itsside, on opening which the revolving shelves are exposed to view. Theshelves can be divided by vertical divisions, so as to form compartmentsfor different articles, and the places of such compartments can beindicated by signs or names made on that part of the ice-reservoir whichprotrudes above the top of the walls of the refrigerator.

My invention enables me to lift the ice-res ervoir, with the shelves,out of the refrigerator, to allow the shelves and the interior, of therefrigerator to be cleaned with facility.

The letter A designates the body of the refrigerator, which is in thisexample cylindrical inform, having double walls, filled as usual -withsuitable non-conducting material. It is provided with a door, B, throughwhich access is had to the shelves of the apparatus. The body A is openat top to receive the icereservoir 0, which consists of a vessel whosebottom converges toward its center, where it terminates in a tube, D,which extends downward centrally through the refrigerator until itenters a drip-pipe, E, arranged in the bottom of the refrigerator. Thetube D acts in conjunction with the drip-pipe, in which it sits, tocenter the ice-reservoir and the array of shelves connected with it. Thetube D serves to carry off the water from the ice-reservoir, and also tosupport the shelves .13, which are arranged upon and around it atsuitable heights or. distances apart, as shown in the drawing. Theshelves are perforated to allow the air to circulate freely, and theirouter edges or peripheries are supported upon vertical air-tubes Gr,which extend downward from an annular air-space, H, formed in the outerpart of the ice-reservoir just below its top. The upper wall or side ofthe air-space H is perforated, as is indicated at h h, to allow acirculation of air between the ice-reservoir and said annular space. Theice-reservoir is closed by a cover, I, and it is provided with handlesJ, by means of which the reservoir and its shelves can be liftedtogether out of the refrigerator, when either the latter or the shelvesare to be cleaned. The ice-reservoir is supported on the top of the wallof the body A of the refrigerator by means of rollers or wheels K,arranged around the exterior of the ice-reservoir in such a manner thatthe reservoir can be turned around upon the wheels at pleasure. Therollers or wheels K are grooved and run upon a circular rail, L, formedon the wall of the refrigerator, so as to aid in keeping theice-reservoir in place.

In order to prevent the water of condensation which collects upon thebottom and sides of the ice-reservoir from falling upon the shelves, Isurround the upper part of the tube D with a drip-cup, M, which catchessuch water of condensation and discharges it into the tube D throughpassages d in the sides of said tube.

The shelves are divided, as may be desired, into divisions orcompartments for different articles, such as milk, butter, meats, &c.Names or signs corresponding to such divisions are arranged upon theexterior exposed part of the ice-reservoir within the same verticallines, in such a manner that when the reservoir is turned so as to bringany of said names over the door of the refrigerator the correspondingcompartment will be opposite the door, and consequently no time need belost in changing the positions of the shelves after the door is opened.The shelf compartments are indicated in dotted outline in Fig. 2.

What I claim as new, and desire to secure by Letters Patent, is-

1. The revolving icechamber G and shelves F, connected togethersubstantially as described, whereby the same can be removed as anentirety out of the case A, as and for the purpose specified.

2. The revolving ice-reservoir O, supporting theshelves F, and air-tubesG, in combination with each other and with the case A, substantially asdescribed, for the purpose specified.

3. The combination, with the ice-reservoir O, of rollers or wheels K,arranged to run upon the top of the refrigerator A, substantially asdescribed.

4. The air-space H, having openings h in its wall, so as to communicatewith the interior of the ice-reservoir, and provided with perforatedair-tubes G, that extend downward into the refrigerator A, substantiallyas described.

This specification signed by me this 30th day of July, 1873.

ALFRED BARDELL.
